USER'S MANUAL
Dear Customer,
We thank you for having chosen a Webasto "Frigo Top" refrigeration system which stands out
for its reliability, quality and technological innovation.
The capillary network of Webasto Authorized Service Centers offers prompt, effective mainte-
nance and technical service. We suggest you keep this manual and, if you sell your vehicle, pass
it on to the new owner. The materials used in the refrigeration system have been have meticulous-
ly selected and only ORIGINAL Webasto SPARE PARTS must be used, obtained through the
vast, capillary network of authorized Webasto service centers. Installing refrigeration system ac-
cessories or spare parts not authorized by Webasto can, in fact, damage the system itself and,
at times, even parts of the vehicle.
Always contact Authorized Webasto Service Center.
And now, ON YOUR WAY with your Webasto "Frigo Top" !!
CAUTION
The manual for control unit is attached to the present publication and is to be
considered an integral part of these instructions.
THE ADVANTAGES OF THE REFRIGERATION SYSTEM
The advantages of the "Frigo Top" Refrigerator are to be found in its functional characteristics.
In fact, the "Frigo Top" Refrigerator lets you transport perishable goods that need a low temper-
ature, refrigerated environment for preservation.
Suitably regulating the system with the thermo regulator installed in the cabin lets you transport
dairy products, fish, eggs, fruit, vegetables, flowers, pharmaceuticals, etc. at a temperature of
0-15 °C, or frozen goods at temperatures between -18 °C and 0 °C. For proper temperature set-
tings, see the indications reported in the tables below.
In the "Frigo Top" refrigeration system the heat regulator can stabilize the desired temperature
inside the refrigeration cell, automatically activating the cooling or heating functions (Only with
R404A gas).

IMPORTANT

While the vehicle is on the road, the refrigeration system runs only while the engine is run-
ning. When the engine is not running, the temperature inside the refrigeration cell is only
guaranteed by the type of insulation installed.
When the vehicle is parked, the temperature inside the refrigeration cell can be correctly
maintained by turning on the "STAND-BY" device. This device is powered with a (230 V or
400 V~) power supply.

HINTS FOR THE BEST WAY TO USE THE REFRIGERATION SYSTEM
Before starting to load the vehicle, pre-refrigerate the goods and bring the temperature inside the
refrigeration cell to the proper temperature. This will prevent interruption of the cold chain.
Air circulation
Load the vehicle being careful to ensure that the cold air produced by the refrigeration unit can
flow freely. There must be a 30 centimeter gap between the goods and the roof of the cell. Do not
block the air outlets or the refrigeration unit supply vents.
IMPORTANT
Open the refrigeration cell as little as possible !
Constantly opening the refrigeration cell brings hot, damp air into the cell causing a drop
in system performance.
Periodically check the cleaning of the condenser. Water "leaking" under the vehicle is due to nor-
mal venting of condensation by the dehumidification system, particularly when the outside air is
hot and humid.
If you feel your refrigeration system is not functioning properly, turn it off immediately and, as soon
as possible, have an Authorized Webasto service station take a look at it.
Never repair the unit on your own. ALWAYS use Authorized Webasto service centers as they
have the necessary original spare parts, technical information and equipment.
